“Apple crushed the PC market in the March quarter, reporting 28% year-over-year growth in Mac unit sales. This compares to IDC’s report of a 3.2% decline in global PC sales for the quarter, meaning that Apple gained significant market share during the quarter. This is even more remarkable considering that IDC reduced its forecast for 2011 PC sales in part because of the impact that another Apple product, the iPad, is having on the PC market.

All told, Apple sold 3.76 million Macs during the quarter, up from 2.94 million Macs in Q2 2010. As you can see in the chart below, Apple has set a new record for Macs sales in the March quarter every year going back to 2003. Indeed, Apple CFO Peter Oppenheimer boasted that Apple has seen year-over-year growth for the last 20 consecutive quarters, each a quarterly record.”
